Carl Weathersby
If you are in the mood for raw, string-bending Albert King style blues, Carl is your man. He played in his band in the '70s.
I have heard him play some of the most raw, harrowing, bone-chilling blues for 40 minutes, snap out of it and play some happy pop song for 3 minutes to rest his psyche, and then go back into the deep blues for another 40 minutes.
